Abstract
The utility model discloses a deflagration-resistant type pipeline flame arrester, comprising a front conical shell and a rear conical shell, wherein a first flange and a second flange are arranged at the upper end and the lower end of the front conical shell; a third flange and a fourth flange are arranged at the upper end and the lower end of the rear conical shell; the second flange is fixedly connected with the fourth flange via a plurality of bolts; flame arresting layers composed of metal fibre fabrics or metal fibre sintered felts are arranged in the front conical shell and the rear conical shell; and the quantity of the plurality of bolts is 4 or 8 or 12. The deflagration-resistant type pipeline flame arrester disclosed by the utility model has the beneficial effects of being simple in structure, reasonable in design, low in manufacturing difficulty, low in production cost, good in sealing effect, free from waste, saved in source, tighter in structure, greatly prolonged in service life and the like.
Description
Technical field
The utility model relates to a kind of spark arrester, relates in particular to a kind of explosion arrestment combustion type flame arrester for pipe.
Background technology
Spark arrester has another name called flame damper, and the effect of spark arrester is to prevent that external flame from scurrying in the equipment that has flammable explosive gas, the pipeline or stop flame to spread at equipment, pipeline enclosure.At present, all there is complex structure in spark arrester commonly used, manufacture difficulty is large, production cost is high, and poor sealing performance, causes the problem such as leakage easily.
The utility model content
For the deficiencies in the prior art, the utility model provides a kind of explosion arrestment combustion type flame arrester for pipe.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of explosion arrestment combustion type flame arrester for pipe, comprise front conical shell and rear conical shell, front conical shell is provided with the first flange and the second flange in two ends up and down, rear conical shell is provided with three-flange and the 4th flange in two ends up and down, the second flange is fixedly connected with by several bolts with the 4th flange, and front conical shell and rear conical shell inside are provided with the flame retardant bed that is comprised of metal fibre interlacement or metallic fiber sintered felt.
Described several bolts are 4 or 8 or 12.
The beneficial effects of the utility model: this utility model is simple in structure, reasonable in design, manufacture difficulty is little, production cost is low; Good sealing effect has been avoided waste, has saved resource; Structure is more fastening, has greatly improved its service life etc.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of explosion arrestment combustion type flame arrester for pipe, comprise front conical shell 1 and rear conical shell 2, front conical shell is provided with the first flange 11 and the second flange 12 in two ends about in the of 1, rear conical shell is provided with three-flange 21 and the 4th flange 22 in two ends about in the of 2, the second flange 12 is fixedly connected with by several bolts 3 with the 4th flange 22, front conical shell 1 and rear conical shell 2 inside are provided with the flame retardant bed that is comprised of metal fibre interlacement or metallic fiber sintered felt, and described several bolts 3 are 4 or 8 or 12.The beneficial effects of the utility model: this utility model is simple in structure, reasonable in design, manufacture difficulty is little, production cost is low; Good sealing effect has been avoided waste, has saved resource; Structure is more fastening, has greatly improved its service life etc.
